I'd bet this whole thing is vibe'd out of nothingness and no human actually thought about whether saying "you are paying for the brand" makes any sense at all.

How the hell are companies and individuals not taking reputational hits for saying blatantly wrong things in AI-voice, under their name?

Also are Gemini and Opus not both big brands? If it was some small ai shop vs opus then sure. So seems indeed to make little sense?
